I use the case for my Samsung Slim Portable Drive and the associated USB cable. The case is not processed completely rigid, but are under pressure with the fingers quite a bit after. But it's already stable and the protection afforded appears appropriate to me. If you open up the case, the hard disk is clamped to the right behind a rubber band, the cable is left in a network to which a rubber band is also sewn. The hard disk is firmly seated right and the net is even more air for longer. A bit thinner the Case would indeed have been, but by the strength there is something more protection for the hard disk. I'm very pleased, especially since the price is very cheap.
